Dynamic Retinal Pathology in Glaucoma Progression Revealed by High‐Resolution Functional Imaging in Vivo

Laser &Photonics Reviews, EarlyView.
In this work, we investigated the dynamic retinal pathology of glaucoma from onset to late stages through longitudinal in vivo high‐resolution imaging in a silicone oil‐induced ocular hypertension (SOHU) glaucoma mouse model. We developed an optimized adaptive optics two‐photon excitation fluorescence microscopy (AO‐TPEFM) technique for morphological ...

Investigating Spatial‐Temporal Optical Emission Spectroscopy of Unstable Positive Leaders in Long Sparks Under Atmospheric Pressure

High Voltage, EarlyView.
ABSTRACT This study explores exciting state species and reaction pathways in positive leaders to better understand the breakdown mechanisms of long air gap discharges and natural lightning. Emission spectra from an unstable positive leader in a 1 m rod‐plate air gap under switching impulse voltages were observed, spanning 300–800 nm.

The importin‐alpha superfamily engages in ethylene signaling by shuttling ETHYLENE INSENSITIVE 2 from the endoplasmic reticulum to the nucleus

The FEBS Journal, EarlyView.
The plant hormone ethylene regulates plant growth, ripening, senescence, and stress responses. The hormonal signal transmission, from receptors at the ER membrane to the transcriptional regulators in the nucleus, is still not completely understood.

Testing Relativistic Effect of Propagation of Gravity by Very-Long Baseline Interferometry

, 2001
It is shown that the finite speed of gravity affects very-long baseline interferometric observations of quasars during the time of their line-of-sight close angular encounter with Jupiter. The next such event will take place in 2002, September 8.

Single‐molecule validation and optimised protocols for the use of secondary nanobodies in multiplexed immunoassays

Journal of Microscopy, EarlyView.
Abstract Recently developed secondary nanobodies or single‐domain antibodies present a powerful tool for immunodetection. Unlike traditional antibodies, their monovalence enables pre‐association with primary antibodies prior to sample staining, presenting a straightforward affinity‐based antibody labelling solution.

Relativistic Signatures of Flux Eruption Events near Black Holes

Galaxies, 2022
Images of supermassive black holes produced using very long baseline interferometry provide a pathway to directly observing effects of a highly curved spacetime, such as a bright “photon ring” that arises from strongly lensed emission.

Search for Compact Extragalactic Radio Sources Near Massive Star Forming Regions [PDF]

, 2006
We have used the Very Large Array to search for compact milliarcsecond-size radio sources near methanol masers in high-mass star-forming regions. Such sources are required for Very Long Baseline Interferometry phase-referencing observations. We conducted

Tacrolimus and Hyaluronate Therapy Enhance Tear Film Stability in Canine Evaporative Dry Eye Disease

Veterinary Ophthalmology, EarlyView.
ABSTRACT Objective Evaluate the efficacy of a therapeutic approach combining tacrolimus and hyaluronate‐based lubricant for the management of evaporative dry eye disease (EDED) in dogs, compared to hyaluronate monotherapy. Procedures Fifty‐four client‐owned dogs with EDED were randomly assigned to three groups (n = 18 each): Group 1 received 0.03 ...
